a.
Disconnect the inner wire from the lever cable clamp.

Disconnect the lever cable from the lever cable anchor.
3.
Feed the lever cable out through the hole in the horizontal back bar of the cart.
You will need to cut the cable tie at the saddle.
4.
Disconnect the brake-release lever from its mounting place.
This will vary, depending on how and where you mounted it.
Adjusting the Lever Cable
The brake lever cable needs to be adjusted so there is no excess slack, but so the brakes are
engaged when the lever is not being actuated.
The brake lever cable should be adjusted at the lever cable clamp, shown in the prededing fig-
ure. There should be just enough slack so the actuator bar touches its hard stop.
Adjusting the Caster Brake Cables
The two caster brake cables are adjusted at the factory. They will normally not need to be adjus-
ted by the user.
If any adjustment is needed, refer to the preceding figure for the adjustment location. The brake
pins should be able to go down as far as the caster surface allows, without any slack.
After the caster cables are adjusted correctly, ensure that the actuator bar just touches its hard
stop. This will keep the actuator bar in position if you have to adjust the lever cable.
Robot Core
The robot core is a sealed unit, with internal fans as the only moving parts.
1.
Access the payload bay. Refer to Accessing the Payload Bay on page 152.
2.
Remove the inner rear cover.
3.
Unlatch and open the battery compartment door, at the rear of the platform.
The battery compartment door is capable of being locked. You may need to unlock it.
4.
Disconnect the battery power and data cables from the rear of the battery.
5.
Disconnect all of the cables that are attached to the top portion of the robot core.
Refer to Standard Platform Connections on page 89.
6.
Remove the core mounting bracket from around the robot core.
This is two pieces, held in place with four screws down into the chassis, with four more
going sideways into the robot core itself. Retain all of these screws for installing the new
robot core.
